RecentlyMobile phonesThe market is bustling, all of themMobile phone manufacturersNew machines have been launched. However, one of the most striking highlights is the brightness of the screen. Xiaomi, OnePlus and Realme have announced theirPhone screenThe brightness broke through 4000nit, 4500nit or even higher. Mobile phone manufacturersOur pursuit of screen brightness is no longer a matter of one or two days, starting from the 2000nit of the iphone15 seriesMobile phone manufacturersThere have been great strides in terms of screen brightness. It seems,Phone screenThe leap in brightness is surprising, but is it a technological innovation or a gimmick?
Phone screenThe increase in brightness is not surprising because:User needsIt has promoted the demand for products, which in turn has promoted the upgrading of the first chain. But,Mobile phone manufacturersThe peak brightness of 4000nit and 4500nit that we call in the promotion is not understood by ordinary consumersPhone screenBrightness. Mobile phone manufacturersWe exaggerate the brightness of the screen, which is actually the "local peak brightness", that is, the maximum brightness when only a part of the screen is lit. It isOLED screenA feature due to the self-illuminating pixelsMobile phonesYou can light up only a subset of pixels, which excites higher brightness. This local peak brightness has an important application in HDR displays.
However, many manufacturers confuse "local peak brightness" and "global peak brightness" in their promotions, and directly use "peak brightness" to advertise, thus misleading consumers into thinking that their screen brightness is far ahead of othersMobile phones。In fact, there is no uniform standard for the definition of local peak brightness, and the data given by manufacturers cannot be directly compared. In addition,Phone screenThe brightness does not directly indicate the quality of the screen, as the maximum brightness setting is based on a variety of factors, including user needs, power consumption, and screen life.
Therefore, for ordinary consumers, the "peak brightness" advertised by manufacturers does not have much reference value. What really needs to be focused is:Mobile phones's automatic brightness adjustment, manual maximum brightness, and global brightness in bright outdoor light. These are the key factors that determine the actual user experience.
AlthoughPhone screenThe leaps and bounds in brightness are amazing, but the "peak brightness" advertised by manufacturers is often exaggerated and has no practical meaning. For the average consumer,Phone screenThe real value of brightness lies in giving the right brightness in the right light environment, ensuring the visibility of the screen display, and not requiring too high peak brightness.
Therefore, consumers buyMobile phonesMore attention should be paid to factors related to the actual experience, such as automatic brightness adjustment, manual maximum brightness, and outdoor visibility. At the same time, be vigilantMobile phone manufacturersThe act of exaggerating the brightness of the screen in the propaganda, understanding that peak brightness is not the only important metric, but more importantly, the overall screen quality and performance should be concerned.
